In oneembodiment, the common electrode CE may be on the first substrate 111.In this case, at least one of the pixel electrode PE or the commonelectrode CE may have a slit structure.

The storage capacitor Cst may include the pixel electrode PE, a storageelectrode branched from a storage line, and an insulation layer betweenthe pixel electrode PE and the storage electrode. The storage line is onthe first substrate 111. Also, the storage line and the gate line GLimay be on the same layer at the same time. The storage electrode maypartially overlap the pixel electrode PE.

The pixel PX may further include a color filter CF to emit light of, forexample, a red, green, or blue color. As an exemplary embodiment, thecolor filter CF may be on the second substrate 112, for example, as inFIG. 3 . In another embodiment, the color filter CF may be on the firstsubstrate 111.

The transistor TR is turned on based on a gate signal provided throughthe gate line GLi. A data voltage received through the data line DLj isprovided to the pixel electrode PE of the liquid crystal capacitor Clcthrough the transistor TR that is turned on. A common voltage is appliedto the common electrode CE.

Electric fields are formed between the pixel electrode PE and the commonelectrode CE based on a difference in voltage level between the datavoltage and the common voltage. Liquid crystal molecules in the liquidcrystal layer LC are controlled by the electric fields between the pixelelectrode PE and the common electrode CE to emit light to form an image.

A storage voltage having a uniform voltage level may be applied to thestorage line. In one embodiment, the common voltage may be applied tothe storage line. The storage capacitor Cst may supplement a voltagecharged in liquid crystal capacitor Clc.

FIGS. 4A and 4B illustrate an embodiment of a connection between thedata lines and pixels, for example, corresponding to the display panelof FIG. 1 . FIG. 4A illustrates pixels PX on a central portion and aleft area LA of the display panel 110. FIG. 4B illustrates pixels PX ona right area RA of the display panel 110.

Referring to FIGS. 4A and 4B, the pixels PX are arranged in a pluralityof rows ROW_1 to ROW_m and a plurality of columns COL_1 to COL_n. Therows ROW_1 to ROW_m extend in the first direction DR1. The columns COL_1to COL_n extend in the second direction DR2. In FIGS. 4A and 4B, thenumber of rows ROW_1 to ROW_m gradually increases upward. The number ofcolumns COL_1 to COL_n gradually increases in a right direction.

The pixels PX may include a plurality of red pixels to emit red light, aplurality of green pixels to emit green light, and a plurality of bluepixels to emit blue light. In one embodiment, the pixels PX may includea plurality of white pixels, a plurality of yellow pixels, a pluralityof cyan pixels, and a plurality of magenta pixels. The pixels PX may bearranged in the order of red, green, and blue pixels in each of the rowsROW_1 to ROW_m, or in a different order in another embodiment.

A number K pixels PX may be in an a-th row of the rows ROW_1 to ROW_m,where a and k are natural numbers. or example, when a is 1, k pixels PXmay be in a first row ROW_1 as illustrated in FIGS. 4A and 4B. Inanother embodiment, the a-th row may be between the first row ROW_1 andan m-th row ROW_m that is the last row. The first row ROW_1 of the rowsROW_1 to ROW_m may be adjacent to the data driver 130. The k pixels PXin the first row ROW_1 may be in a g-th column COL_g to a p-th columnCOL_p between a first column COL_1 and an n-th column COL_n that is thelast column. The values g and p are natural numbers, where g is greaterthan 1, p is greater than g, and n is greater than p.

Referring to FIGS. 4A and 4B, k pixels PX having the same number as thepixels PX in the first row ROW_1 may be in the m-th row ROW_m. In oneembodiment, pixels PX of a number greater than pixels PX in the firstrow ROW_1 may be in the m-th row ROW_m.

The k pixels PX in the first row ROW_1 may be a reduced or minimumnumber of pixels in the rows ROW_1 to ROW_m. In FIGS. 4A and 4B, k=9 butk may be a different number in the first row ROW_1 in anotherembodiment.

The number n pixels PX may be in each of an e-th row ROW_e to an f-throw ROW_f of the rows between the first row ROW_1 and the m-th rowROW_m. In one embodiment, the number n is greater than k, e and f arenatural numbers, e is greater than 1, f is equal to or greater than e,and m is greater than f.

The n pixels PX in each of the e-th row ROW_e to the f-th row ROW_f maybe a greater or maximum number of pixels PX of the pixels PX in the rowsROW_1 to ROW_m. In FIGS. 4A and 4B, n=27 but may be a different numberin each of the e-th row ROW_e to the f-th row ROW_f in anotherembodiment. In one embodiment, pixels PX of a number greater than k andless than n may be in each of the remaining rows, except for the firstrow ROW_1, the m-th row ROW_m, and the e-th row ROW_e.

The number of pixels PX in a present row in the rows between the firstrow ROW_1 and the e-th row ROW_e may be equal to or greater than thenumber of pixels PX in a former row. In one embodiment, the number ofpixels PX in a present row may be the same as the number of pixels PX inthe former row.

The number of pixels PX in a present row in rows between the f-th rowROW_f and the m-th row ROW_m may be equal to or less than that of pixelsPX in a former row. For example, the number of pixels PX disposed in anf+2-th row may be the same as that of pixels PX in an f+1-th row, andthe number of pixels PX in an f+3-th row may be less than that of pixelsPX disposed in the f+2-th row.

A number L data lines may be in each of first areas A1, whichcorresponds to an area between adjacent pixels PX in the first row ROW_1and an area adjacent to one side of the pixel PX in one column of thefirst column and the last column of the first row ROW_1, where L is anatural number. For example, an area adjacent to a right side of thepixel PX in the p-th column COL_p, that is the last column of the firstrow ROW_1, may be or include the first area A1.

The number L may be a value based on dividing the maximum number ofpixels PX of the pixels PX in the rows ROW_1 to ROW_m by the minimumnumber of pixels PX. For example, L may be a value based on dividing nby k. In this case, the number L corresponds to a share of the valueobtained by dividing n by k. If a remaining value does not exist when nis divided by k, L data lines may be in each of the first areas A1.However, if a remaining value exists when n is divided by k, other orremaining data lines may be additionally in the first areas A1.

The data lines DL1 to DLn may include a plurality of data line groupsDLG which respectively include L data lines. For example, as illustratedin FIGS. 4A and 4B, when n=27 and k=9, L may be determined as 3. Thus, 3data lines may be in each of the first areas A.

The data lines DL1 to DLn extend in the second direction DR2 in thefirst areas A1. The data lines DL1 to DLn in the first areas A1 extendto the data driver 130 in the second direction DR2 and are connected tothe data driver 130.

The data line groups DLG include a plurality of straight lines SDL and aplurality of bent data lines BDL. The straight lines SDL may be firstdata lines of the L data lines of each of the data line groups DLG. Thebent data lines BDL may be data lines except for the straight lines SDL.

The straight data lines SDL may extend in the second direction DR2 andbe connected to the pixels PX in the corresponding column of the g-thcolumn COL_g to the p-th column COL_p. In the first row ROW_1 to thee-th row ROW_e, the bent data lines BDL may be bent twice to extend inthe second direction DR2, the first direction DR1, and the seconddirection DR2. The bent data lines BDL extend from the e-th row ROW_2 inthe second direction DR2.

The bent data lines BDL may extend to be bilaterally symmetrical to eachother with respect to a predetermined area of a central portion of thedisplay panel 110. The bent data lines BDL may include first to v-thbent data lines BDL1 to BDLv and be connected to the pixels PX that arenot connected to the straight data lines SDL.

An area of the display panel 110, which is disposed at a left side withrespect to the central portion of the display panel 110 in the firstdirection DR1, may corresponding to a left area LA of the display panel110. An area of the display panel 110, which is disposed at a right sidewith respect to the central portion of the display panel 110 in thedirection DR1, may correspond to a right area RA of the display panel110.

An embodiment of the left area LA of the display panel 110 is in FIG.4A, and an embodiment of the right area RA of the display panel 110 isin FIG. 4B. The pixels PX in the central portion of the display panel110 may be arranged in the form of the matrix and may be pixels PX in ag+3-th column to a g+5-th column.

In the first row ROW_1 to the e-th row ROW_e, the number of pixels PX inan h-th row may be different from the number of pixels PX in an h+1-throw, where h is a natural number. In this case, the bent data lines BDLhaving the same number as a difference between the number of pixels PXin the h-th row and the number of pixels PX in the h+1-th row may extendin the first direction DR1 between the pixels PX in the h-th row and thepixels PX in the h+1-th row.

The bent data lines BDL bent from the second direction DR2 to the firstdirection DR1 to extend may be bent from the first direction DR1 to thesecond direction DR2 to extend. Each of the bent data lines BDLextending from the first direction DR1 to the second direction DR2 maybe connected to the pixels PX in the corresponding column of the columnsCOL_1 to COL_n.

The bent data lines BDL in first areas A1 successively extend from thesecond direction DR2 to the first direction DR1, while increasing inorder of the bent data lines BDL from the first bent data line BDL1.Also, the bent data lines BDL in the first areas A1 successively extendfrom the second direction DR2 to the first direction DR1, whileincreasing in order of the bent data lines BDL from a v-th bent dataline BDLv.

When the number of pixels PX in the h+1-th row is greater, by c, thanthe number of pixels PX in the h-th row in the left area LA of thedisplay panel 110 and the first row ROW_1 to the e-th row ROW_e, c bentdata lines BDL may extend between the pixels PX in the h-th row and thepixels PX in the h+1-th row in the first direction DR1 in the left areaLA of the display panel 110 and the first row ROW_1 to the e-th rowROW_e, where c is a natural number.

When the number of pixels PX in the h+1-th row is greater, by d, thanthe number of pixels PX in the h-th row in the right area RA of thedisplay panel 110 and the first row ROW_1 to the e-th row ROW_e, d bentdata lines BDL may extend between the pixels PX in the h-th row and thepixels PX in the h+1-th row in the first direction DR1 in the right areaRA of the display panel 110 and the first row ROW_1 to the e-th rowROW_e, where d is a natural number.

For example, the number of pixels PX in the first row RWO_1 may be 9 andthe number of pixels PX in the second row may be 15. A difference valuebetween the number of pixels PX in the first row RWO_1 and the number ofpixels PX in the second row is 6. Thus, 6 bent data lines BDL may extendin the first direction DR1 between the pixels PX in the first row RWO_1and the pixels PX in the second row.

Since the pixels are bilaterally symmetrical to each other in FIGS. 4Aand 4B, c and d may have the same value, e.g., a value of 3. In oneembodiment, when the pixels PX are not bilaterally symmetrical to eachother, c and d may have different values.

When c and d have the same value (e.g., 3), three bent data lines BDLmay successively be bent to extend from the second direction DR2 to thefirst direction DR1, while increasing in order of the bent data linesBDL from the first bent data line BDL1. Also, three bent data lines BDLmay successively be bent to extend from the second direction DR2 to thefirst direction DR1, while decreasing in order of the bent data linesBDL from the v-th data line BDLv.

In the left area LA of the display panel 110, a first bent data lineBDL1, a second bent data line, and a third bent data line of the bentdata lines BDL in the first area A1 to extend in the second directionDR2 are successively bent to extend in the first direction DR1 betweenthe pixels PX in the first row ROW_1 and the pixels PX disposed in thesecond row.

In the right area RA of the display panel 110, a v-th bent data lineBDL1, a v−1-th bent data line, and a v−2-th bent data line of the bentdata lines BDL in the first area A1 to extend in the second directionDR2 are successively bent to extend in the first direction DR1 betweenthe pixels PX disposed in the first row ROW_1 and the pixels PX disposedin the second row.

Since the number of pixels PX in the second row is 15 and the number ofpixels PX in a third row is 19, a difference value between the number ofpixels PX in the second row and the number of pixels PX in the third rowis 4. In the left area LA and the right area RA of the display panel110, fourth and fifth bent data lines and v−3-th and v−4-th bent datalines may successively be bent to extend in the first direction DR1between the pixels PX in the second row and the pixels PX in the thirdrow.

The bent data lines BDL may be bent to extend from the second directionDR2 to the first direction DR1 in the first row ROW_1 to the e-th rowROW_e through the foregoing manner. The bent data lines BDL extending inthe first direction DR1 are successively bent to extend from the firstdirection DR1 to the second direction DR2 from the first bent data lineBDL1 and the v-th bent data line BDLv.

Each of the bent data lines BDL bent to extend from the first directionDR1 to the second direction DR2 is connected to the pixels PX in thecorresponding column of a first column COL_1 to a g−1-th column and ap+1-th column to n-th column COL_n. The bent data lines BDL bent toextend from the first direction DR1 to the second direction DR2 areconnected by a column unit to the pixels PX successively disposed in ane−1-th column to the first column COL_1 from the first bent data lineBDL1 and connected by a column unit to the pixels PX successivelydisposed in a p+1-th column to n-th column COL_n from the v-th bent dataline BDLv.

For example, in the left area LA of the display panel 110, the first,second, and third bent data lines extending in the first direction DR1between the pixels PX arranged in the first row ROW_1 and the pixels PXin the second row are successively bent to extend from the firstdirection DR1 to the second direction DR2. In the left area LA and theright area RA of the display panel 110, the first, the second, and thethird bent data lines extending from the first direction DR1 to thesecond direction DR2 are successively connected by a column unit to thepixels PX in an e−1-th to e−3-th columns.

The first bent data line BDL1 extends from the first direction DR1 tothe second direction DR2 and is connected to the pixels PX arranged inthe corresponding e−1-th column of the first column COL_1 to the e−1-thcolumn. The second bent data line extends from the first direction DR1to the second direction DR2 and is connected to the pixels PX arrangedin the corresponding e−2-th column of the first column COL_1 to thee−1-th column. The third bent data line extends from the first directionDR1 to the second direction DR2 and is connected to the pixels PXarranged in the corresponding e−3-th column of the first column COL_1 tothe e−1-th column.

In the right area LA of the display panel 110, the v-th, the v−1-th, andthe v−2-th bent data lines BDL may extend in the same manner and aresuccessively connected by the column unit to the pixels PX in a p+1-th,a p+2-th, and a p+3-th columns. Other or remaining ones of the bent datalines BDL may be connected to other or remaining ones of the pixels inthe same manner.

For example, the bent data lines BDL may successively extend in thesecond direction DR2, the first direction DR1, and the second directionDR2 from the first bent data line BDL1 and the v-th bent data line BDLv.In one embodiment, the bent data lines BDL may extend in the seconddirection DR2, the first direction DR1, and the second direction DR2.

FIG. 5 illustrates an embodiment of L data lines in one first area ofFIG. 4A. FIGS. 6 to 8 are views illustrating an example of a distancebetween pixels in adjacent rows in FIGS. 4A and 4B. Each of FIGS. 6 to 8illustrates an example of pixels in two rows in the left area LA of thedisplay panel 110 and in the first row ROW_1 to the e-th row ROW_e.

Referring to FIG. 5 , L data lines DLj, DLj+1, and DLj+2 in the firstarea A1 of the first row ROW_1 extend in the second direction DR2 andare at the same distance in the first direction DR1. The data linesadjacent to each other of the data lines DLj, DLj+1, and DLj+2 may bespaced a first distance GP1 from each other in the first direction DR1in the first area A1.

Each of the data lines DLj, DLj+1, and DLj+2 has a predetermined widthWD in the first direction DR1. The distance of sides of the data linesadjacent to each other of the L data lines DLj, DLj+1, and DLj+2 in thefirst direction corresponds to a pitch PT. The pitch PT may be based ona sum of the first distance GP1 and the width WD.

Referring to FIGS. 6 to 8 , the pixels PX have the same size. The pixelsPX in an h-th row and the pixels PX in an h+1-th row are arranged in thefirst direction DR1. The distance between the pixels PX in adjacent rowsin the second direction DR2 on the display panel 110 may correspond to asecond distance GP2.

The second distance GP2 may be equal to or greater than the product ofthe pitch PT and the maximum value of a difference value in number ofpixels PX in the rows adjacent to each other on the left area LA and inthe first row ROW_1 to the e-th row ROW_e or a difference value innumber of pixels PX disposed in the rows adjacent to each other on theright area RA and in the first row ROW_1 to the e-th row ROW_e.

As described with reference to FIGS. 4A and 4B, when the pixels PX arebilaterally symmetrical to each other, c and d may have the same value.In the left area LA of the display panel 110 and the first row ROW_1 tothe e-th row ROW_e, a difference value in the number of pixels PX inrows adjacent to each other may be 1 to 3. In the right area RA of thedisplay panel 110 and the first row ROW_1 to the e-th row ROW_e, adifference value in the number of pixels PX in rows adjacent to eachother may be 1 to 3.

The maximum value of the difference value in number of pixels PX in therows adjacent to each other on the left area LA of the display panel 110and in the first row ROW_1 to the e-th row ROW_e and the differencevalue in number of pixels PX in the rows adjacent to each other on theright area RA of the display panel 110 and in the first row ROW_1 to thee-th row ROW_e is 3. Thus, the second distance GP2 may be equal to orgreater than the product of the pitch PT and the value of 3.

When h=1, as illustrated in FIG. 6 , the second distance GP2 between thepixels PX in the first row ROW_1 and the pixels PX in the second rowROW_2 may be equal to or greater than the product of the pitch PT andthe value of 3, e.g., GP2>PT×3. When h=2, as illustrated in FIG. 7 , thesecond distance GP2 between the pixels PX in the second row ROW_2 andthe pixels PX in the third row ROW_3 may be equal to or greater than theproduct of the pitch PT and the value 3.

When h is e−1, as illustrated in FIG. 8 , the second distance GP2between the pixels PX in an e−1-th row ROW_e−1 and the pixels PX in ane-th row ROW_e may be equal to or greater than the product of the pitchPT and the value 3. The second distance GP2 between pixels PX inadjacent rows and other or remaining rows may also be equal to orgreater than that obtained by multiplying the pitch PT by 3.

The pixels PX may not be disposed bilaterally symmetrical to each other.For example, in the left area LA of the display panel 110 and the firstto e-th rows ROW_1 to ROW_e, a difference value in number of pixels PXin adjacent rows may be 1 to 4. In the right area RA of the displaypanel 110 and the first to e-th rows ROW_1 to ROW_e, a difference valuein number of pixels PX in adjacent rows may be 1 to 3. In this case, thesecond distance GP2 may be equal to or greater than the product of thepitch PT and the value 4.

When an L number of data lines DL1 to DLn are not between the pixels PXof the first row ROW_1, but are disposed one-by-one between the pixelsPX of the first row ROW_1, the data lines not between the pixels PX mayextend via the non-display area NDA on which the pixels PX are notdisposed. Since the space of the non-display area NDA, in which the datalines that are not disposed between the pixels PX that are disposed, isto be secured, the bezel area of the non-display area may increase.

In an embodiment, L number of data lines DL1 to DLn are between thepixels PX of the first row ROW_1. As a result, the bezel area may bereduced. Thus, the display apparatus 100 may realize a narrow bezel.

FIG. 9 illustrates a cross-sectional view of an area B1 of FIG. 4Aaccording to one embodiment. Referring to FIG. 9 , one data lineextending in the second direction DR2 may cross at least one data lineextending in the first direction DR1. The data lines that extend in thefirst and second directions DR1 and DR2 and cross may be insulated fromeach other. For example, a j-th data line DLj extending in the seconddirection DR2 may cross a j+1-th data line DLj+1 extending in the firstdirection DR1. The j+1-th data line DLj+1 of the j-th data line DLj andthe j+1-th data line DLj+1, which cross each other, may include a bridgeelectrode BE, a first sub line SL1, and a second sub line SL2.

A first insulation layer INS1 is on the first substrate 111, and thej-th and j+1-th data lines DLj and DLj+1 are on the first insulationlayer INS1. The first sub line SL1 and the second sub line SL2 of thej+1-th data line DLj+1 are disposed with the j-th data line DLjtherebetween. A second insulation layer INS2 is on the first insulationlayer INS1 and covers the j-th and j+1-th data lines DLj and DLj+1.

The bridge electrode BE of the j+1-th data line DLj+1 is on the secondinsulation layer INS2. The bridge electrode BE and the data line DLj maybe disposed with the second insulation layer INS2 therebetween. Thebridge electrode BE passes through the second insulation layer INS2 andis connected to the first and second sub lines SL1 and SL3 throughcontact holes CH, which expose predetermined areas of the first andsecond sub lines SL1 and SL2.

Since the first sub line SL1 and the second sub line SL3 areelectrically connected to each other through the bridge electrode BE,the j-th data line DLj extending in the second direction DR2 and thej+1-th data line DLj+1 extending in the first direction DR1 areinsulated from each other, even though they cross.

FIGS. 10A and 10B illustrate an embodiment of a connection between datalines and pixels of a display panel. Difference points for theconnection between the data lines DL1 to DLn and the pixels PX in FIGS.4A and 4B and for the connection between data lines DL1 to DLn andpixels PX will be described. For example, FIG. 10A illustrates pixels PXin a central portion and a left area LA of a display panel 110_1. FIG.10B illustrates pixels PX in a right area RA of the display panel 110_1.

Referring to FIGS. 10A and 10B, the pixels PX are arranged in rows ROW_1to ROW_m and columns COL_1 to COL_n. Each of the pixels PX in each ofthe row ROW_1 to ROW_m is connected to a corresponding data line of thedata lines DL1 to DLn. The number of pixels PX in each of the first rowROW_1 to an m-th row ROW_m is k. The number of pixels in each of an e-throw ROW_e to an f-th row ROW_f is n. The number of pixels PX in each ofother or remaining rows may be less than n and greater than k. In theexamples of FIGS. 10A and 10B, k=9 and n=25.

The number of pixels PX in the present row in the rows between the firstrow ROW_1 and the e-th row ROW_e may be equal to or greater than thenumber of pixels PX in a former row. The number of pixels PX in thepresent row in the rows between the f-th row ROW_f and the m-th rowROW_m may be equal to or less than the number of pixels PX in a formerrow.

A number L data lines corresponding to a value obtained by dividing n byk may be in first areas A1, respectively. A remaining value may beobtained from dividing n by k, e.g., dividing n by k is b, where b datalines may be additionally disposed one-by-one in b first areas A1, whereb is a natural number.

A number L+1 data lines may be in each of the b first areas A1 of thefirst areas A1, and the L data lines may be in each of the other orremaining first areas A1. The number L+1 data lines are successivelydisposed in w first areas A1 from the most left side of the first areasA1 and successively disposed in b-w first area A1 from the most rightside, where w is an integer equal to or greater than 0 and is equal toor less than b.

For example, in the examples of FIGS. 10A and 10B, since n=25 and k=9, avalue obtained by n by k is 2 and the remaining value is 7. Thus, L us 2and b is 7. Also, two data lines are in each of the first areas A1. Whenw is 4, 4 data lines of 7 data lines are successively disposed,one-by-one, in 4 first areas A1 from the most left side of the firstareas A1. Other or the remaining 3 data lines of 7 data lines may besuccessively disposed, one-by-one, on 3 first areas A1 from the mostright side of the first areas A1.

An extending manner of the data lines DL1 to DLn and a distance betweenthe pixels in an h-th row and the pixels in an h+1-th row may besubstantially the same as those, for example, described with referenceto FIGS. 4A, 4B, and 5 to 8 .

For example, as illustrated in FIGS. 4A and 4B, straight data lines SDLin the first areas A1 may extend in the second direction DR2 and beconnected to the pixels in a corresponding column of column COL_1 toCOL_n. Bent data lines BDL may extend in the second direction DR2, thefirst direction DR1, and the second direction DR2 and be connected tothe pixels in a corresponding column of the column COL_1 to COL_n.

As illustrated in FIGS. 6 to 8 , a second distance GP2 between thepixels PX in rows adjacent to each other in the second direction DR2 onthe display panel 110_1 may be equal to or greater than that obtained bymultiplying the pitch PT by the maximum value of a difference value innumber of pixels PX in the rows adjacent to each other on a left area LAof the display panel 110_1 and in the first row ROW_1 to the e-th rowROW_e or a difference value in number of pixels PX in the rows adjacentto each other on a right area RA of the display panel 110_1 and in thefirst row ROW_1 to the e-th row ROW_e.

In the display apparatus including the display panel 110_1 of FIGS. 10Aand 10B, since L or L+1 data lines may be between the pixels PX of thefirst row ROW_1, a bezel area may be reduced.

FIG. 11 illustrates another embodiment of a display apparatus 200, andFIG. 12 illustrates an embodiment of pixels and data lines in an area A2of the display panel of FIG. 11 . For example, FIG. 12 illustratespixels PX and data lines, which are in the left area of a display panel210 in a left side with respect to a central area of the display panel210. The display panel 210 may have a structure that is bilaterallysymmetrical, e.g., pixels PX and data lines in a right area of thedisplay panel 210 may be symmetrical to those in the left area of thedisplay panel 210. Pixels PX in a central area of the display panel 210may be arranged in the form of a matrix.

Referring to FIGS. 11 and 12 , the display apparatus 200 includes thedisplay panel 210, a gate driver 220, a data driver 230, and a flexiblecircuit board 240. The display panel 210 includes a plurality of pixelsPX, a plurality of gate lines GL1 to GLm connected to the pixels PX, anda plurality of data lines DL1 to DLn.

The gate lines GL1 to GLm extend in a first direction DR1 and areconnected to the gate driver 220 in an non-display areas NDA at a leftside of the display panel 210. The data lines DL1 to DLn are connectedto the data driver 230. The data driver 230 is mounted on the flexiblecircuit board 240 and connected to the non-display area NDA at a lowerend of the display panel 210.

The display apparatus 200 may have the same constituent elements as thedisplay apparatus 100 of FIG. 1 , except for the shape of the displaypanel 210 and an arrangement of the pixels PX according to the shape ofthe display panel 210.

The display panel 210 may have a shape similar to that of a rearviewmirror of a vehicle. The display panel 210 includes a first side S1extending in the first direction DR1, a second side S2 extending in thefirst direction DR1 facing the first side S1 and having a length lessthan the first side S1, a third side S3 connecting one side of the firstside S1 to one side of the second side S2, and a fourth side S4connecting the other side of the first side S1 to the other side of thesecond side S2. Each of a predetermined area of each of both sides ofthe third side S3 and a predetermined area of each of both sides of thefourth side S4 has a curved shape that protrudes to the outside.

The display panel 210 includes a display area DA and a non-display areaNDA surrounding the display area DA. The pixels PX may be arranged in aplurality of rows and plurality of columns in the display area DA. Ana-th row may be a first row ROW_1, and k pixels PX may be in the firstrow ROW_1. A number n pixels PX may be in each of an e-th row ROW_e toan f-th row ROW_f of the rows between the first row ROW_1 and an m-throw ROW_m.

A number r pixels PX number greater than the number k may be in the m-throw ROW_m, where r is a natural number that is greater than k and lessthan n. The pixel PX having number greater than k and less than n may bein each of rows between the first row ROW_1 and an e-th row ROW_e. Anumber of pixels PX less than n and greater than r may be in each ofrows between an f-th row ROW_f and the m-th row ROW_m.

The number of pixels PX in a present row, in the rows between the firstrow ROW_1 and the e-th row ROW_e, may be equal to or greater than thenumber of pixels PX in a former row. The number of pixels PX in apresent row, in the rows between the f-th row ROW_f and the m-th rowROW_m, may be equal to or less than the number of pixels PX in a formerrow.

The arrangement of the data lines DL1 to DLn, the extending manner ofthe data lines DL1 to DLn, and the distance between the pixels PX in anh-th row and the pixels PX in an h+1-th row may be substantially thesame as in FIGS. 4A, 4B, 5 to 8, 10A, and 10B, except for a shape of thedisplay panel 210.

For example, like the arrangement of data lines DL1 to DLn in FIGS. 4Aand 4B, L data lines corresponding to a value obtained by dividing n byk may be in each of the first areas A1 of the first row ROW_1. However,when a remaining value obtained by dividing n by k exists, like thearrangement of data lines DL1 to DLn in FIGS. 10A and 10B, b data linescorresponding to the remaining value may be additionally disposed,one-by-one, in each of the first areas A1.

Straight data lines SDL may extend in the second direction DR2 and beconnected to pixels PX in a corresponding column of the columns. Bentdata lines BDL may extend in the second direction DR2, the firstdirection DR1, and second direction DR2 and may be connected to pixelsin a corresponding column of the columns.

As illustrated in FIGS. 6 to 9 , a second distance GP2 between thepixels PX in the rows adjacent to each other in the second direction DR2on the display panel 210 may be equal to or greater than that obtainedby multiplying a pitch PT by the maximum value of a difference value innumber of pixels PX in the rows adjacent to each other in a left area LAof the display panel 210 and in the first row ROW_1 to the e-th rowROW_e or a difference value in number of pixels PX disposed in the rowsadjacent to each other on a right area RA of the display panel 210 andin the first row ROW_1 to the e-th row ROW_e.

In the display apparatus 200, L data lines are between the pixels PX ofthe first row ROW_1. As a result, the bezel area may be reduced.

FIG. 13 illustrates another embodiment of a display apparatus 300, andFIG. 14 illustrates an embodiment of pixels and data lines in a displaypanel of FIG. 13 . Referring to FIGS. 13 and 14 , the display apparatus300 includes a display panel 310, a gate driver 320, a data driver 330,and a flexible circuit board 340. The display panel 310 includes aplurality of pixels PX, a plurality of gate lines GL1 to GLm connectedto the pixels PX, and a plurality of data lines DL1 to DLn.

The gate lines GL1 to GLm extend in a first direction DR1 and areconnected to the gate driver 320 in an non-display areas NDA at a rightside of the display panel 310. The data lines DL1 to DLn are connectedto the data driver 330. The data driver 330 is mounted on the flexiblecircuit board 340 and connected to the non-display area NDA at a lowerend of the display panel 310.

The display apparatus 300 may have the same constituent elements as thedisplay apparatus 100 of FIG. 1 , except for a shape of the displaypanel 310 and an arrangement of the pixels PX according to the shape ofthe display panel 310.

The display panel 310 may have a shape similar to that of goggles. Forexample, the display panel 310 includes a first side S1_1 extending inthe second direction DR2, two second sides S1_2 connected to differentsides of the first side S1_1 to extend in the first direction DR1, andtwo curved sides CS1 facing the first side S1_1 and each of which has acurved shape. The curved sides CS1 have sides connected to each other.Each of the curved sides CS1 has one side connected to an end of acorresponding second side S1_2 of the second sides S1_2. Each of thecurved sides CS1 has a curved shape that protrudes to the outside of thedisplay panel 310.

The pixels PX may be arranged in a plurality of rows ROW_1 to ROW_m anda plurality of columns COL_1 to COL_n. An a-th row ROW_a may be a rowbetween a first row ROW_1 and an m-th row ROW_m. A number k pixels PXmay be in the a-th row ROW_a. A number n pixels PX may be in each of ane-th row ROW_e to an f-th row ROW_f of the rows between the first rowROW_1 and the a-th row ROW_a. A number n pixels PX may be in each of aq-th row ROW_q to an u-th row ROW_u of the rows between the a-th rowROW_a and the m-th row ROW_m. The numbers q an u are natural numbers, uis greater than q, and m is greater than u.

The number of pixels in the first row ROW_1 and the m-th row ROW_m maybe r that is greater than k. The pixels PX having number that is greaterthan k and less than n may be in each of the rows between the a-th rowROW_a and the q-th row ROW_q and the rows between the a-th row ROW_a andthe f-th row ROW_f. The pixels PX having number that is greater than rand less than n may be in each of the rows between the first row ROW_1and the e-th row ROW_e and the rows between the u-th row ROW_u and them-th row ROW_m. In FIGS. 14 , k=7 and n=14.

The number of pixels PX in a present row, in the rows between the firstrow ROW_1 and the e-th row ROW_e, may be equal to or greater than thenumber of pixels PX in a former row. The number of pixels PX in apresent row, in the rows between the f-th row ROW_f and the a-th rowROW_a, may be equal to or less than the number of pixels PX in a formerrow.

The number of pixels PX in a present row, in the rows between the a-throw ROW_a and the q-th row ROW_q, may be equal to or greater than thenumber of pixels PX in a former row. The number of pixels PX in apresent row in the rows between the u-th row ROW_u and the m-th rowROW_m may be equal to or less than that of pixels PX in a former row.The pixels PX may be vertically symmetrical to each other in the seconddirection DR2 with respect to the a-th row ROW_a.

L data lines may be in each of the first areas A1 of the a-th row ROW_.Straight data lines SDL may extend in the second direction DR2 and beconnected to the pixels in a corresponding column of the columns COL_1to COL_n. Bent data lines BDL may be bent at least two times and mayextend from the second direction DR2 to the first direction DR1 and fromthe first direction D1 to the second direction DR2 and be connected tothe pixels in a corresponding column of the columns COL_1 to COL_n.

Since k=7 and n=s 14, L is 2. Two data lines may be in each of the firstareas A1 of the a-th row ROW_a, and the data lines may extend in thesecond direction DR2 on the first areas A1.

The pixels PX may not be bilaterally symmetrical to each other. Forexample, the pixels PX in the row on the right area of the display panel310 may have the same number, and the pixels in the rows on the leftarea of the display panel 310 may have numbers different from eachother. Thus, the value d provided as an example in FIGS. 4A and 4B maynot exist, and only the value c may exist.

In this case, in the first row ROW_1 to the q-th row ROW_q, the datalines having the same number as a difference between the number ofpixels PX in the h-th row and the number of pixels PX in the h+1-th rowmay extend in the first direction DR1 between the pixels PX in the h-throw and the pixels PX in the h+1-th row, where z is a natural number.

The bent data lines BDL in the first areas A1 successively extend fromthe second direction DR2 to the first direction DR1 from the first bentdata line BDL1 of the bent data lines BDL. The bent data lines BDL, bentfrom the second direction DR2 to the first direction DR1, may besuccessively bent from the first direction DR1 to the second directionDR2.

For example, in the f-th row ROW_f to the a-th row ROW_a, when adifference value between the number of pixels PX in the h-th row and thenumber of pixels PX in the h+1-th row is z, z bent data lines BDL mayextend in the first direction DR1 between the pixels PX in the h-th rowand the pixels PX in the h+1-th row. Each of the z bent data lines BDLextending in the first direction DR1 may extend from the first directionDR1 to the second direction DR2 and be connected to the pixels PX in acorresponding column of the columns COL1 to COLn.

For example, a difference between the number of pixels PX in an a−1-throw and the number of pixels PX in the a-th row ROW_a may be 3. Thefirst to third bent data lines of the bent data lines BDL extending inthe second direction DR2 on the first areas A1 may successively extendin the first direction DR1 between the pixels PX in the a−1-th row andthe a-th row ROW_a.

The first to third bent data lines extending in the first direction DR1may successively extend from the first direction DR1 to the seconddirection DR2. Each of the first to third bent data lines BDL extendingfrom the first direction DR1 to the second direction DR2 may beconnected to the pixels PX in the corresponding column.

The number of pixels PX in an a−2-th row and the number of pixels PX inthe a−1-th row may be the same. Thus, the bent data line BDL extendingin the first direction DR1 between the pixels PX in the a−2-th row andthe pixels PX in the a−1-th row do not exist.

In other or remaining rows, except for the a-th to a−2-th rows of thef-th row ROW_f to the a-th row ROW_a, the bent data lines BDL except forthe first to third bent data lines may extend from the second directionDR2 to the first direction DR1 in the same manner, and then extend inthe second direction DR2. This manner may be substantially the same asthe extending manner of the data lines DL1 to DLn described withreference to FIGS. 4A and 4B.

Also, in the e-th row ROW_e to the first row ROW_1, when a differencevalue between the number of pixels PX in the h-th row and the number ofpixels PX in the h+1-th row is z, the bent data lines BDL extend in thefirst direction DR1 between the pixels PX in the h-th row and the pixelsPX in the h+1-th row. For example, since a difference between the numberof pixels PX in the e−1-th row and the e-th row ROW_e and the number ofpixels PX in the e−2-th row and the e−1-th row is 1, one bent data lineBDL extends in the first direction between the pixels PX in the e−1-throw and the pixels PX in the e-th row ROW_e and between the pixels PX inthe e−2-th row and the pixels in the e−1-th row. Other bent data linesBDL may be connected in the same manner.

In the e-th row ROW_e to the first row ROW_1, the bent data lines BDLmay successively extend from the second direction DR2 to the firstdirection DR1 from the bent data line BDL at the most left side. Forexample, the bent data line BDL extending in the second direction DR2between the pixels PX in the first column COL_1 of the e-th row ROW_eand the pixels PX in the second column may extend in the first directionDR1 between the pixels PX in the e−1-th row and the pixels PX in thee-th row ROW_e.

Next, the bent data lines BDL extending in the second direction DR2between the pixels PX in the second column of the e-th row ROW_e and thepixels PX in the third column may extend in the first direction DR1between the pixels PX in the e−2-th row and the pixels PX in the e−1-throw. Other bent data lines BDL may be connected in the same manner.

In the e-th row ROW_e to the first row ROW_1, the bent data lines BDLextending in the first direction DR1 may extend in the second directionDR2 at positions corresponding to positions of the bent data lines BDLin the a-th row ROW_a. For example, a v-th bent data line BDLv isadjacent to a right side of the pixel PX of the n-th column COLn of thea-th row ROW_a.

In the e-th row ROW_e to the first row ROW_1, the v-th bent data lineBDLv extending in the first direction DR1 may be adjacent to the rightside of the pixels PX in the n-th column COLn of the e−1-th row ROW_e−1to the first row ROW_1 to extend in the second direction. Other bentdata lines BDL may be connected in the same manner. In on embodiment, inthe e-th row ROW_e to the first row ROW_1, the bent data lines BDLextending in the first direction DR1 may be in various columns of thee-th row ROW_e to the first row ROW_1 to extend in the second directionDR2.

In the a-th row ROW_a to the q-th row ROW_q, when a difference valuebetween the number of pixels PX in the h-th row and the number of pixelsPX in the h+1-th row is z, z bent data lines BDL may extend in the firstdirection DR1 between the pixels PX in the h-th row and the pixels PX inthe h+1-th row. Thereafter, the straight data lines SDL may extend inthe second direction DR2 and be connected to the pixels PX in acorresponding row. This manner may be substantially the same as thatdescribed with reference to FIGS. 4A and 4B.

The second distance GP2 between the pixels PX in the rows adjacent toeach other in the second direction DR2 on the display panel 310 is equalto or greater than that obtained by multiplying a pitch PT by themaximum value of a difference value in number of pixels in the rowsadjacent to each other in the first row ROW_1 to the q-th row ROW_q ofthe display panel 110. For example, in the first row ROW_1 to the q-throw ROW_q, since the maximum value of the difference value in number ofpixels PX in the rows adjacent to each other is 3, the second distanceGP2 is equal to or greater than that obtained by multiplying the pitchPT by 3.

The data lines DL1 to DLn from the q-th row ROW_q to the m-th row ROW_mextend in the second direction DR2. However, in the e-th row ROW_e tothe first row ROW_1, the bent data lines BDL extends from the seconddirection DR2 to the first direction DR1 and then extends from thesecond direction DR2 to the first direction DR1. The data lines DL1 toDLn may be connected to the data driver 330 adjacent to the first rowROW_1 via a space between the pixels PX of the first row ROW_1.

The data lines DL1 to DLn having a predetermined number may be betweenthe pixels PX of the first row ROW_1 and connected to the data driver330 to reduce the bezel area of the display apparatus 300.

FIGS. 15A and 15B illustrate another embodiment of a connection betweendata lines and pixels of a display panel. FIGS. 16 to 18 illustrate anexample of a distance between the pixels in the rows adjacent to eachother in the second direction in FIGS. 15A and 15B. For example, FIG.15A illustrates pixels PX in a central portion and a left area LA of adisplay panel 410. FIG. 15B illustrates the pixels PX in a right area RAof the display panel 410. Each of FIGS. 16 to 18 illustrates examples ofpixels PX in two rows on the left area LA of the display panel 410 andin a first row ROW_1 to an e-th row ROW_e.

Referring to FIGS. 15A and 15B, pixels PX are arranged in a plurality ofrows ROW_1 to ROW_m and a plurality of columns COL_1 to COL_n. Thearrangement of pixels PX may be substantially the same as the pixels PXin FIGS. 4A and 4 b.

L data lines may be in each of first areas A1 of the first row ROW_1. InFIGS. 15A and 15B, since k=9 and n=28, L may be 3. The data lines DL1 toDLn extend in the second direction DR2 on the first areas A1. Anintermediate data line DLc of the data lines DL1 to DLn extends in thesecond direction DR2. Other or remaining data lines, except for theintermediate data line DLC, may be bent data lines BDL.

In the first row ROW_1 to the e-th row ROW_e, the bent data lines BDLmay be bent at least two times and may extend from the second directionDR2 to the first direction DR1, and then from the first direction DR1 tothe second direction DR2. The bent data lines BDL extend from the e-throw ROW_2 in the second direction DR2. The bent data lines BDL may havea bent shape that is symmetrical to each other with respect to theintermediate data line DLc.

For example, in the first row ROW_1 to the e-th row ROW_e, the bent dataline adjacent to a left side of the intermediate data line DLc may bebent to extend from an upward direction of the second direction DR2 to aleft direction of the first direction DR1, and then from the leftdirection of the first direction DR1 to the upward direction of thesecond direction DR2. In the first row ROW_1 to the e-th row ROW_e, thebent data line adjacent to a right side of the intermediate data lineDLc may be bent to extend from an upward direction of the seconddirection DR2 to a right direction of the first direction DR1, and thenfrom the right direction of the first direction DR1 to the upwarddirection of the second direction DR2.

In the first row ROW_1 to the e-th row ROW_e, a first bent data lineBDL1 may repeatedly extend in an upward direction of the seconddirection DR2, the left direction of the first direction DR1, and theupward direction of the second direction DR2. In the first row ROW_1 tothe e-th row ROW_e, a v-th bent data line BDLv may repeatedly extend inthe upward direction of the second direction DR2, the right direction ofthe first direction DR1, and the upward direction of the seconddirection DR2.

Thus, the bent configuration of the bent data line adjacent to the leftside of the intermediate data line DLc and the bent data line adjacentto the right side of the intermediate data line may be symmetrical toeach other. Also, the bent configuration of the first bent data lineBDL1 and the v-th bent data line BDLv may be symmetrical to each other.Also, the bent configuration of other bent data lines BDL may besymmetrical to each other with respect to the intermediate data lineDLc.

In the first row ROW_1 to the e-th row ROW_e, the bent data lines BDLhaving a predetermined number of the bent data lines BDL may extend inthe first direction DR1 between the pixels PX in the h-th row and theh+1-th row. In the first row ROW_1 to the e-th row ROW_e, as the numberof rows increases, the number of bent data lines BDL extending from thesecond direction DR2 to the first direction DR1 may increase. Forexample, although the number of bent data lines extending in the firstdirection DR1 between the pixels PX in the first row ROW_1 and thepixels PX in the second row is 8, the number of bent data lines BDLextending in the first direction DR1 between the pixels PX in the secondrow and the pixels PX in the third row increases to 14.

As the number of rows increases, the number of bent data lines BDLextending in the first direction DR1 may increase. The number of bentdata lines BDL extending in the first direction between the pixels PX inthe e−1-th row and the pixels PX in the e-th row ROW_e may be increasedor maximized.

Each of the bent data lines BDL extending in the first direction betweenthe pixels PX in an h-th row and the pixels PX in an h+1-th row may beconnected to the pixels PX in a t-th column corresponding to extend inthe second direction between the corresponding t-th column and a t+1-thcolumn of columns of the h+1-th row. For example, four bent data linesextending in the first direction between the pixels PX in the first rowROW_1 and the pixels in the second row may be respectively disposedbetween first and second columns, between second and third columns,between third and fourth columns, and between fourth and fifth columnsof the columns of the second row to extent in the second direction DR2.

The bent data lines extending in the second direction DR2 arerespectively connected to the pixel PX in the first column, the pixel PXin the second column, the pixel in the third column, and the pixel PX inthe fourth column of the columns of the second row. Other bent datalines BDL may also extend in the same manner and be connected to thepixels PX.

Each of the pixels PX in each of the rows in the first row ROW_1 to thee−1-th row may be connected to a corresponding bent data line BDL of thebent data line BDL. The intermediate data line DLc may not be connectedto the pixels PX in the first row ROW_1 to the e−1-th row. In the e-throw ROW_e to the m-th row ROW_m, the data lines DL1 to DLn extend in thesecond direction DR2 and are connected to the pixels in a correspondingcolumn of the columns COL1 to COLn.

Referring to FIGS. 16 to 18 , a second distance GP2 between the pixelsPX in the rows adjacent to each other in the second direction DR2 on thedisplay panel 410 may be equal to or greater than that obtained bymultiplying a pitch PT by a value calculated by adding one to themaximum value of a difference value in number of pixels PX in the rowsadjacent to each other on a left area LA of the display panel 410 and inthe first row ROW_1 to the e-th row ROW_e or a difference value innumber of pixels PX in the rows adjacent to each other on a right areaRA of the display panel 410 and in the first row ROW_1 to the e-th rowROW_e.

The maximum value of the difference value in number of pixels PX in therows adjacent to each other on the left area LA of the display panel 410and in the first row ROW_1 to the e-th row ROW_e and the differencevalue in number of pixels PX of the display panel 410 adjacent to eachother on the right area RA and in the first row ROW_1 to the e-th rowROW_e is 3. Thus, the second distance GP2 is equal to or greater thanthat obtained by multiplying the pitch PT by 4.

When h=1, as illustrated in FIG. 16 , the second distance GP2 betweenthe pixels PX in the first row ROW_1 and the pixels PX in the second rowROW_2 may be equal to or greater than that obtained by multiplying thepitch PT by 4. When h=2, as illustrated in FIG. 17 , the second distanceGP2 between the pixels PX in the second row ROW_2 and the pixels PX inthe third row ROW_3 may be equal to or greater than that obtained bymultiplying the pitch PT by 4.

When h is e−1, as illustrated in FIG. 18 , the second distance GP2between the pixels PX in an e−1-th row ROW_e−1 and the pixels PX in ane-th row ROW_e may be equal to or greater than that obtained bymultiplying the pitch PT by 4. The second distance GP2 between thepixels PX in the rows adjacent to each other in other or remaining rowsof the display panel 410 may also be equal to or greater than thatobtained by multiplying the pitch PT by 4.

As described in FIGS. 4A and 4B, a difference value between the numberof pixels PX in the first row ROW_1 to the e-th row ROW_e of the displaypanel 410 and in the h-th row on the left and right areas LA and RA andthe number of pixels PX in the h+1-th row may be c and d. In FIGS. 15Aand 15B, since the pixels PX are bilaterally symmetrical to each other,c and d may have the same value.

In this case, line routing parts LRP having the same number as thatobtained by adding 1 to one value of c and d may be defined between thepixels PX in the h-th row and the pixels PX in the h+1-th row. The linerouting part LRP extends in the first direction DR1. (For convenience ofdescription, the line routing parts LRP are illustrated by dashed dottedlines in FIGS. 16 and 18 ). Each of the line routing parts LRP may have,for example, the same width as that WD of each of the data lines.

As illustrated in FIG. 16 , a difference value between the number ofpixels PX in the first row ROW_1 and the number of pixels in the secondrow ROW_2 on the left area LA of the display panel 410 is 3. Thus,fourth line routing parts LRP may be between the pixels PX in the firstrow ROW_1 and the pixels PX in the second row ROW_2.

As illustrated in FIG. 17 , a difference value between the number ofpixels PX in the second row ROW_2 and the number of pixels in the thirdrow ROW_3 on the left area LA of the display panel 410 is 2. Thus, threeline routing parts LRP may be between the pixels PX in the second rowROW_2 and the pixels PX in the third row ROW_3.

As illustrated in FIG. 18 , a difference value between the number ofpixels PX in the e−1-th row ROW_e−1 and the number of pixels in the e-throw ROW_e on the left area LA of the display panel 410 is 1. Thus, twoline routing parts LRP may be between the pixels PX in the e−1-th rowROW_e−1 and the pixels PX in the e-th row ROW_e.

When the pixels PX are not bilaterally symmetrical to each other, c andd may have values different from each other. In this case, the linerouting parts LRP having the same number as that obtained by adding 1 toa relatively large value of c and d may be between the pixels PX in theh-th row and the pixels PX in the h+1-th row.

The bent data lines BDL extending in the first direction DR1 extend viathe line routing parts LRP. For example, as illustrated in FIG. 16 , thebent data lines BDL extending in the first direction DR1 between thepixels PX in the first row ROW_1 and the pixels in the second row ROW_2may extend via four line routing parts LRP.

As illustrated in FIG. 17 , the bent data lines BDL extending in thefirst direction DR1 between the pixels PX in the second row ROW_2 andthe pixels in the third row ROW_3 may extend via three line routingparts LRP. As illustrated in FIG. 18 , the bent data lines BDL extendingin the first direction DR1 between the pixels PX in the e−1-th rowROW_e−1 and the pixels in the e-th row ROW_e may extend via two linerouting parts LRP.

In the display panel 410 of FIGS. 15A and 15B, since L data lines DL1 toDLn are between the pixels PX of the first row ROW_1, the bezel area maybe reduced.
